DISPENSER FOR DISPENSING A PREDETERMINED QUALITY OF A COSMETICPREPARATION BACKGROUND OF THE INVENTION The present invention relates toa dispenser for dispensing a predetermined quantity of a cosmeticpreparation.

Synthetic-plastic containers holding a portion of a hair preparation,for example, are known in the prior art. These very cheap containers,which are opened by cutting or tearing off the cap, or closure, and arediscarded after being emptied, have the disadvantage that they areextremely unpleasant looking; and for this reason beauty parlors, andsimilar establishments, are reluctant to show them to their customers.These establishments prefer to use crystal decanters, which must becontinuallyrefilled, since they are too expensive to discard. But ittakes time to refill the decanters, which therefore are disliked by theestablishment owners.

SUMMARY OF THE INVENTION It is an object of the present invention toprovide a cosmetic dispenser which combines the advantages of knowndispensers, while avoiding their disadvantages.

It is another object of the present invention to provide a dispenserhaving a replaceable, discardable refill container housed within ahollow holder.

BRIEF DESCRIPTION OF THE DRAWING FIG. 2 is a side elevational view of arefill container suitable for the holder illustrated in FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawingsand more'particularly to FIG. 1, the dispenser for a hair preparationcomprises an attractive outer holder 1 and an exchangeable refillcontainer 2 fitting in the holder. The refill container is a knownconically-shaped, synthetic-plastic receptacle containing a portion ofhair shampoo. To empty the refill container of its contents, thecontainer cap 3 is cut off and the sides of the container are squeezed.Since the container 2 is not attractive, it is held concealed in theholder 1 until emptied, as illustrated in dot-dash line in FIG. 1.

The outer holderl comprises a slightly conically-shaped body or jacket 4made of a suitable, elastically flexible synthetic plastic, such as ahighor low-pressure polyethylene, a polypropylene, a copolymer, or someother flexible or rubberlike material. The inner surfaceat the lower endof the body 4 is provided with threads 5, into which is screwed a bottommember 7 having mating threads 6. The bottom member embodies a supportpart comprising a centrally disposed, vertical cylindrical projection orneck 8 that supports the refill container 2. The upper part of theholder body 4 is formed with a radially inwardly extending shoulder 9. Acontainer 2 is inserted into the holder 1 through the lower end thereof,and

thereafter, the bottom member 7 is screwed into place, and a narrowannular section of the upper part of the wall of the container 2 ispressed against the inwardly directed shoulder 9, as shown in FIG. 1.The upward pressure of the bottom member 7 causes the latter and thebottom of the container 2 v .When the container 2 is to be emptied, thecap 10 is screwed off, the cap 3 cut off, and the flexible holder body 4is squeezed. Afterwards, the empty container 2 is removed and discarded,and a fresh refill container is loaded into the holder 1. The jacket 4has a bottom portion 12 which is substantially cylindrical to providethe interior screw threads 13 which engage with the screw threads 5 ofthe cylindrical bottom member 7. However, the bottom portion is slightlyof convex shape, pressing inwardly at its lowermost portion 16 againstthe lowermost portion of the bottom member 7. The bottom member 7includes an outer cylindrical portion 14 having the outer screw threads5 therein and a circular disc 15 thereof is connected to and adjacentthe lowermost portion 16 of the outer cylindrical portion 14. Thecylindrical neck 8 extends vertically upwardly from the center of thecircular disc 15. The bottom member 7 further includes a centraldownwardly projecting extension 17 depending from the lower side of thecircular disc 15 as well as a frustoconical leg 18 extending downwardlyfrom the periphery of the disc 15 and widening in the downwarddirection. The diameter of the cylindrical neck 8 is substantiallysmaller than its length, and is substantially smaller than the diameterof the outer cylindrical portion 14 of the bottom member 7.

Even though it is necessary to replace only the very inexpensive refillcontainer 2, the container is always housed, and ready for use, in anattractive holder. This is particularly advantageous for hairdressers,and similar establishments, which have a fastidious clientele. Theholder is advantageously decorated with designs in color or withsuitable lettering of a pleasing appearance.

It will be understood by those in the art that the present invention isuseful as a dispenser for all fluid cosmetic preparations that can bedispensed from a container by squeezing the sides thereof.

I claim:

1. A dispenser, for dispensing a predetermined amount of a cosmeticpreparation, comprising: 7

an outer container made of an elastic yielding synthetic material andincluding an elastic yielding compressible, jacket;

an exchangeable container adapted to hold a predetermined amount of acosmetic preparation therein and made of a flexible plastic material,and removably positioned inside said outer container, adjacent saidcompressible jacket;

said exchangeable container including means for providing a dispensingopening through which said cosmetic preparation is to be dispensed;

said compressible jacket for being compressed, squeezing saidexchangeable container, thereby forcing said cosmetic preparationthrough said dispensing opening;

said jacket including a bottom portion having av bottom openingincluding screw threads adjacent thereto;

said exchangeable cartridge adapted to be inserted and removed,respectively, through said bottom opening;

a screw threaded bottom memberrem ovably screwed into said bottomopening and including a yieldable support part on which saidexchangeable container is supported;

said support part comprising a long cylindrical neck resilientlypressing said exchangeable container against said jacket therebyproviding a shake proof holding of said exchangeable cartridge in saidouter container;

said bottom portion of said jacket is substantially cylindrical andcooperatively with said screw threaded bottom member is rigid in theaxial direction;

said cylindrical neck of said bottom member is axially;

yieldable;

said bottom member includes an outer cylindrical portion having outerscrew threads thereon and a circular disc said outer cylindricalportion;

said cylindrical neck extends vertically upwardly from the 7 center ofsaid circular disc;

lowermost portion against the lowermost portion of said frustoconicalleg; and

the diameter of said cylindrical neck is substantially smaller than thelength thereof as well as substantially smaller than the diameter ofsaid outer cylindrical portion of said bottom member.
